The materials foam pump used for plastic packaging bottles are usually pp, pe, K material, as, abs, acrylic, pet, etc. The cream jars, lotion bottles, caps, stoppers, gaskets, pump heads, and dust caps commonly used in the cosmetics and daily necessities market are injection molded; pet blowing bottles are molded in two steps: first of all, they are made by injection molding Tube embryos are then made into finished products by blowing; other containers have thinner emulsion bottles and washing bottles as blowing bottles. The pet material is environmentally friendly, has high barrier properties, light weight, not easy to break, chemical resistance, high transparency and other characteristics. It is suitable for making pearlescent, colored, magnetic white, transparent and other packaging bottles. It is widely used in gel water filling.

The acrylic material is an injection bottle, which has poor chemical resistance. Generally, it cannot be directly filled with paste. It needs to be equipped with an inner liner to block. The filling should not be too slow to prevent the paste from entering the liner and the acrylic run and then cracking; Acrylic cream After scratching the bottle, it is obvious that the bottle is free, and all the requirements are higher in packaging and transportation; acrylic bottles also have high permeability, thick sensory walls and generous, but the price is expensive. as transparency is higher than abs, and toughness is better. Production and ordering instructions for plastic packaging materials Mold production costs: Pe and pet blow mold development costs are generally 1500-4000 yuan; injection mold development costs are 8000-20000 yuan; mold development selection material stainless steel is more expensive than alloy materials, but Stainless steel materials are durable and durable; mold development generally produces several sets at a time, which can be customized according to customer production needs.

Generally, the minimum order quantity of plastic packaging materials is not less than 5000 users. The packaging color can be customized by users. It is usually made of primary colors frosted and magnetic white. It can also be added with pearlescent powder effects. Generally, the main container and the cover must be equipped with the same color masterbatch. However, in the production process, because the container is the same as the selected material part with the lid, the appearance of the color effect will be different.The materials used for surface silk screen printing are ordinary ink and uv ink. The uv ink has better effect, gloss and three-dimensional sense. Customers should first confirm the board during production. The silk screen effect on different material containers will be different. Gold foil, silver foil and other processing techniques are different from gold powder and silver powder in effect.

The hard and smooth surface of the main container is suitable for gold foil or silver foil. The soft surface of the container is not good for ironing and printing, and it is easy to fall off; Better gloss than printing process. The silk screen film must first produce a negative film, the graphic effect is black, the background color is transparent, the hot stamping and silver foil process is a positive film, the graphic effect is transparent, and the background color is black; the text and pattern ratio of the film is too small too Fine, otherwise hot stamping will not produce the effect. The matching caps of plastic packaging bottles are generally equipped with inner gaskets, pull caps, inner plugs, and very few are also equipped with small spoons or droppers. The main consideration is their tightness and ease of use.
